Abstract Tamoxifen-induced radioresistance, reported in vitro, might pose a problem for patients who receive neoadjuvant tamoxifen treatment and subsequently receive radiotherapy after surgery. Previous studies suggested that
DNA damage repair or cell cycle genes are involved, and could therefore be targeted to preclude the occurrence
of cross-resistance. We aimed to characterize the observed cross-resistance by investigating gene expression
of DNA damage repair genes and cell cycle genes in estrogen receptor-positive MCF-7 breast cancer cells that
were cultured to tamoxifen resistance. RNA sequencing was performed, and expression of genes characteristic
for several DNA damage repair pathways was… More >
